DRAFT-EVEN ER.

SPECIFICATION forming part of Letters Patent No. 744,177, dated November17, 1903.

Application filed February 2,1903. Serial No. 141,490. (No model.)

To all whom it may concern.-

Be it known that we, CURTIS 0. DILLAVON and WILLIAM D. DILLAVON,citizens of the United States, residing at Clinton, in the county ofDewitt and State of Illinois, have invented certain new and usefulImprovements in Draft-Eveners, of which the following is aspecification.

The object of our invention is to provide a simple but effectivedraft-evener for such implements as binders, gang-plows, and sulkyplowsthat will evenly distribute the draft to the teams attached thereto; andwith this and minor objects in view our invention consists of the partsand combination of parts, as will be hereinafter more fully set out.

In the drawings, Figure 1 is a top plan view of our improveddraft-evenersuitably secured to a plow-beam for purposes ofillustration. Fig. 2 is a sectional view of the same on the line 2 2,Fig. 1, parts being shown in elevation.

3 represents a plow-beam broken away, which is used merely for purposesof illustration in showing the method of attachment of our improveddraft-evener to the vehicle.

4 is a clevis of any approved pattern, which is adjustably secured tothe forward end of the beam 3.

5 is an arm rigidly secured at one end to the clevis 4. and extendingbodily to one side of the beam 3, as clearly shown in Fig. 1. This armis provided with a loop'7, pivoted to the center thereof, to which isattached one end of a chain 8, the other end of the chain being suitablysecured at 9 to the beam,whereby said arm is rigidly held at rightangles to the beam 3..

10 is a draft-lever pivoted to the arm 5 by means of the bolt passingthrough the loop 7,

.and it will be noticed in this connection that the pivot-point of thedraft-lever is to one side of the center of the same, said draft-leverbeing provided on the extreme end of its shorter arm with a loop 11,within which is journaled a pulley 12. To the longer arm of I thedraft-lever is suitably pivoted a doubletree 13, to each end of which ispivoted a swingletree 14. 15 is a doubletree, to which are suitablysecured at its ends swingletrees 16. This doubletree 15 is connected tothe arm 5 by means of a rope or chain 17, one end of which is connectedto the doubletree 15, thence passed around the pulley 12 of thedraft-lever 10, and finally secured at its other end to the arm 5, asillustrated in Fig. 1.

The operation of the device is obvious, and it will be seen that theparts are so constructed and secured relatively to each other that teamsattached to the plow must pull an equal share of the draft, inasmuch asone of the teams is pulling from one end of the draftlever 10 direct,while the other is pulling direct from the outer end of the arm 5 bymeans of therope or chain 17, and by reason of the connection of the arm5 by the clevis and chain 8 to the arm 3 each team will have an equalleverage, the direct pull being immediately at the end of the plow-beam.

Having thus described our invention, the following is what we claim asnew:

1. In a draft-evener, the combination with the beam, an arm rigidlysecured thereto at one end, and extending bodily at right angles tosaidbeam, of a draft-lever eccentrically pivoted to the center of said arm;and douend of said draft-lever, and a doubletree secured to the outerend of said arm, and having connection with the other end of thedraftlever.

3. The combination with a beam and an arm secured at one of its ends tosaid beam, and extending at right angles thereto, a connection betweenthe center of said arm and The foregoing specification signed this 22dsaid beam, of a draft-lever between the cenday of January, 1903.
